Glendale, AZ (KOLD) - Arizona Cardinals quarterback Carson Palmer announced his retirement Tuesday afternoon, just one day after head coach Bruce Arians did he same.

In a letter released by the team, Palmer wrote, in essence, that the time was right for him to hang up his cleats.

A 15-year NFL vet who played for Cincinnati, Oakland, and Arizona, Palmer finishes his Cardinals career fourth all-time in franchise history for passing yards (16,782) and touchdowns (105). He ranks 12th all-time in the NFL for both of those categories.

As Darren Urban noted, with Palmer's retirement, the Cardinals are now without a quarterback under contract for 2018 as all three remaining (Drew Stanton, Blaine Gabbert, and Matt Barkley) will become free agents.
